Leading up to the big Vista launch later this year (hopefully), NVIDIA have set up a mailout newsletter which keeps one informed of all the latest happenings regarding NVIDIA's affiliation with the highly anticipated Microsoft project.
To register your e-mail address for the mailouts, enter it at the bottom of this page on NVIDIA's website. You'll notice there's a bunch of links to the left of the page leading to stacks of other relative info as well.
Worthy of mentioning from the first mailout a couple of days ago, NVIDIA have linked up a few podcasts for your listening pleasure. They are "PC gaming on Windows Vista", "Are you ready for Windows Vista?" and "NVIDIA Unveils Extreme High Definition Gaming". You can also get to the podcasts using iTunes by clicking on this link.
